Last time I replaced the brakes/rotors I noticed chips of ceramic falling
out from the pistons on the front brake calipers of '99 4x4 Durango. Can
they be rebuilt or should I replace the whole caliper. I'm getting ready to
do another pad/rotor replacement and figured this would be the time. Where
would the best value to get parts or replacements.

They can, but it's often easier, quicker, and even cheaper to just buy a set
of remanufactured calipers (these have already been rebuilt). They should
run about $30 a piece, and there will be a core charge for you to return
your old calipers. You can often save a little more by buying 'loaded'
calipers - meaning they also come with pads.
As far as where to purchase, any auto parts store will do.
But - that aside... brake pad material falling out from the pistons isn't a

behind the pistons that absorb the heat from the pads. Don't know Mopars
though. All I know about Durangos is they have weak front end components,

believe the Raybestos pads have a lifetime warrantee, which appears to be
about 35,000 miles. china rotors are only $19 so they are a disposable item.
